Check Digit Verification of cas no
The CAS Registry Mumber 96882-98-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,8,8 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 96882-98:
(7*9)+(6*6)+(5*8)+(4*8)+(3*2)+(2*9)+(1*8)=203
203 % 10 = 3
So 96882-98-3 is a valid CAS Registry Number.

Enantioselective synthesis of (R)-propylene carbonate from ethyl (S)-lactate
Whitaker, John M.,Ronald, Robert C.
experimental part, p. 1403 - 1404 (2010/02/16)
We report a three-step synthesis of (R)-propylene carbonate from inexpensive, chiral ethyl (S)-lactate. The synthesis involves a borohydride ester reduction and an unusual intramolecular displacement reaction by a carbonate anion. The procedure is simple and reliable, resulting in (R)-propylene carbonate in approximately 60% overall yield with ≥98% ee. Georg Thieme Verlag Stuttgart.
